The finale of series one ties up certain stories. We have seen Sidney being distressed by his wartime memories. He finally tells Sidney what happened and why he blames himself for the death of one of his soldier's.
Sidney also tells his German girlfriend Hildegard that he has strayed with a jazz singer. Sidney is moping that Amanda is getting married. In fact he gets drunk and makes an embarrassing scene.
It is all pretty soapy stuff. As far as the mystery is concerned, Geordie is shot while investigating another shooting of a policeman.
While he is in hospital Sidney pokes his nose about and it leads to a local building magnate, Heath who was a commanding officer in the war. The two shootings are linked to him somehow. Sidney gets an answer from a person who served under Heath, he is also badly affected like Sidney with his memories of the war. Something Heath did causes him torment.
The mystery itself is simple maybe because the series wants to tie up some loose ends. There was nothing much taxing here, it is just easy viewing but it lacked the fun of Father Brown.
